Checking the Condition of the Punch Chip Case

The punch chip case detection mechanism consists of the punch chip case full sensor mounted to the side of the punch chip
case and a prism found inside the case.
The punch chip case sensor, on the other hand, is used to check the presence/absence of the punch chip case.
The chips occurring as the result of punching operation are collected in the punch chip case, and are monitored by a reflection
type sensor (punch chip case full sensor). When the case becomes full with chips, the main controller PCB suspends punching
operation between stacks (Memo), resuming the operation when the case is put back in place.

NOTE:
If the punch chip case is found to be full when the 2nd sheet of the 3rd set is being handled while making 5 sets of 5 copies, the
machine continues to operate until the 3rd set is complete, suspending its operation at the start of the 4th set.
